Добрый день, господа!
Купил новый маршрутизатор DSL-G225 и он сразу разочаровал меня частыми разрывами сессии PPPoE. ADSL линия работает прекрасно, параметры линии в пределах хороших, скорость соответствует тарифу. Тем не менее разрывы сессии PPPoE бывают чуть ли не каждую минуту.

1. Параметры линии ADSL:

Состояние линии: Подключено
Скорость входящего потока:5608 Кбит/с
Скорость исходящего потока:624 Кбит/с
Link Power State:L0
Режим:G.DMT
Trellis:ON
Состояние линии:No Defect

Параметр Up Down
Скорость 624 Кбит/с 5608 Кбит/с
Расчётная скорость 1416 Кбит/с 6593 Кбит/с
Соотношение сигнал/шум 27.0 дБ 26.9 дБ
Затухание 200 дБ 285 дБ
Выходная мощность 12.2 дБм 19.8 дБм

2. Журнал событий (Сообщения об ошибках) с маршрутизатора.

Прошу Вас помочь с проблемой.

Очень сильное затухание, 200/285 это не нормально
Затухание линии:
до 20 dB — отличная линия
от 20 dB до 40 dB — рабочая линия
от 40 dB до 50 dB — возможны сбои
от 50 dB до 60 dB — периодически пропадает синхронизация
от 60 dB и выше — оборудование работать не будет

С уважением, Легаев Евгений.

У этой модели маршрутизатора просто неправильное отображение разрядности именно затухания (я не знаю почему так, наверное, программная ошибка в прошивке). На самом деле затухание на линии 20/28,5. Это подтверждается, если я ставлю маршрутизатор ADSL 2750U.
Так что не в этом дело.
Жду другую причину от специалистов.
Тем более, что Линк не рвется во время разрыва сессии PPPoE (лампочка ADSL горит постоянно, а гаснет только лампочка INTERNET).

Сделайте самый детальный лог (отладочный уровень)

Да, сделайте более детальны лог "Отладочные сообщения" и в настройках соединения включите "Отладка РРР"
И какая версия прошивки установлена на модеме?

С уважением, Легаев Евгений.

Включил "Отладка РРР", сделал лог "Отладочные сообщения".

Вот первые результаты. Такое ощущение, что сессия рвется после большого количества вторжений за короткое время. Т.е., когда вторжения идут с периодичностью менее одной минуты.

Версия прошивки: 2.5.9

А индикатор dsl гаснет в момент разрыва ppp-сессии?
И, кстати, вот вопрос:

G.DMT он сам выбрал или вы вручную поставили? Если автомат, то линия действительно плохая. Понаблюдайте за параметрами линии в динамике. Возможно они меняются во времени. Если вы вручную поставили только G.DMT, то включите другие варианты модуляции.
И так, на всякий случай: сплиттер же у вас конечно подключен?
ps. И параллельных телефонов, подключенных до сплиттера, тоже нет?

Индикатор ADSL вообще не гаснет. В момент разрыва PPP-сессии ADSL тоже не гаснет, гаснет только индикатор INTERNET.

Все режимы модуляции включены по умолчанию (заводские настройки).
Ниже привожу варианты включенных режимов (вместо галочки пишу плюсики)...
Включить G.Dmt: +
Включить G.lite: +
Включить T1.413: +
Включить ADSL2: +
Включить AnnexL: +
Включить ADSL2+: +

Видимо, G.Dmt, выбрано маршрутизатором автоматически.
Пробовал разные варианты модуляции ставить вручную, разрывы сессии PPP не прекращаются.
Параметры ADSL линии неоднократно смотрел в динамике. Всё время цифры неизменны. Меняется иногда значение соотношение сигнала/шума на Down на +/- 0,1. При разрыве сессии PPP значения параметры линии также не меняются.

Ни телефона, ни сплиттера в линии нет. Маршрутизатор включен непосредственно к телефонной линии напрямую.

Я бы сплиттер поставил всё-таки. Не зря ж он G.DMT включает. Путается в частотах.
А уж если точно определять, то надо подставить временно другой модем. Но только точно так же - без сплиттера)) Вот тогда совсем понятно станет.

Сплиттер поставил. Посмотрим, что изменится....

Первый результат - режим G.DMT остался.
Второй результат - чуть немного поднялся сигнал/шум на +0,7 до 27,6.
Третий результат - разрывы сессии PPP не прекратились.

Поставил для эксперимента другой маршрутизатор ADSL 2750U.

Этот маршрутизатор выдает такие параметры ADSL линии:

Состояние линии: Подключено
Скорость входящего потока:5608 Кбит/с
Скорость исходящего потока:624 Кбит/с
Link Power State:L0
Режим:G.DMT
Trellis:ON
Состояние линии:No Defect

Параметр Up Down
Скорость 624 Кбит/с 5608 Кбит/с
Расчётная скорость 1404 Кбит/с 13256 Кбит/с
Соотношение сигнал/шум 26.0 дБ 28.4 дБ
Затухание 18.5 дБ 29.0 дБ
Выходная мощность 12.2 дБм 20.0 дБм

Как видим, режим тот же G.DMT, параметры линии почти такие же (отличие на +/- 0,5).
Разрывов сессии PPP нет.

В настройках маршрутизатора ADSL 2750U также поставил "Отладка PPP" и журнал "Отладочные сообщения".
